摘　　要：在永磁同步电机(PMSM)无传感器控制技术的基础上,提出了家用电器PMSM的恒功率控制算法。计算功率后通过卡尔曼滤波得到精确的功率值,并设计具有跟踪功能的功率控制环路,自适应地实现PMSM的最大功率控制。完成了控制器和驱动器的设计。实际测试结果表明,该方法可使洗衣机电机保持最大功率运行。Based on the sensorless control technology of permanent magnet synchronous motor(PMSM),a constant power control algorithm for the PMSM of household electrical appliances is put forward.In the proposed method,the calculated motor power is adjusted with Kalman filtering to achieve high precision,and a power control loop with power tracking functionality is designed,so as to adaptively realize the maximum power control of the PMSM.The design of controller and motor drive is implemented.Test results show that,with the proposed method,the washing machine motor can keep working at the maximum power status.
